My father is getting elderly plus forgetful… I’ve taken him to the nurse however they don’t feel it is Alzheimer’s. They feel he is just getting old, then he still can take care of himself though. He just forgets things he was told plus he forgets them truly frequently. Then, on Monday, he called me plus told me that his furnace wasn’t working right. He said it was making a lot of noise plus not putting out much heat. I called up a furnace service supplier plus busy a service for Monday. Then I went over to my father’s condo just before the furnace supplier arrived. They looked around a bit plus then removed the air filter. “Here is your problem,” the contractor said. I could see that the air filter was just full of dust plus dog hair. It looked like it hadn’t been changed in months, maybe even years, and my father said he forgot to change it. I took the heating contractor aside plus asked about a service plan. I was hoping that maybe the heating supplier could come plus change the air filter every 2 months or so. It turns out that that would be rather valuable. Instead, the contractor proposed that he install a smart air filter plus affix it with my iPhone. Then, the air filter will let me know when it is time to change it, additionally, I could sign up for a service plan where the heating supplier comes out every 6 months. That makes a lot of sense. I don’t want my father’s furnace to stop working because he forgets to take care of it.
